Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a noise reduction device for bridge construction used in bridge engineering. Background Art

[0002] A bridge is a structure built to span natural or man-made obstacles. It spans rivers, lakes, and seas, allowing vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure, and ancillary structures. The superstructure primarily refers to the span structure and support system; the substructure includes abutments, piers, and foundations; and ancillary structures include the bridgehead slab, tapered slope protection, revetments, and diversion works.

[0003] At present, during the construction of bridges passing between high-rise buildings, in order to prevent construction noise from disturbing residents, noise reduction devices are often used to fence off the construction site.

[0004] However, the noise reduction enclosures used in bridge construction in the existing technology are mostly made of plates with an inward-curved top. The inward-curved part of the top blocks the upward noise. However, due to the different heights of the bridges, the noise intensity experienced by residents located above the bridge side is higher, and the adjustable noise blocking cannot be guaranteed, making the noise reduction effect relatively limited. In view of this, we propose a noise reduction device for bridge construction used in bridge projects. Utility Model Content

[0005] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a sound reduction device for bridge construction used in bridge engineering, so as to solve the technical problem that the sound reduction enclosures currently used in bridge construction mostly block upward noise through the inward curved part of the top. Due to the different heights of the bridges, the residents located above the side of the bridge are exposed to higher noise intensity, and the adjustable noise blocking cannot be guaranteed, resulting in a relatively limited sound reduction effect.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a sound reduction device for bridge construction used in bridge engineering, comprising a sound insulation board and an arc-shaped inward-bending component detachably installed on the top of the sound insulation board; the sound insulation board is provided with a winding component on the curved side toward the arc-shaped inward-bending component, and a rope is installed between the arc-shaped inward-bending component and the winding component, and a first support frame and a second support frame are respectively constructed on both sides of the bottom of both sides of the sound insulation board.

[0007] Furthermore, the arc-shaped inward-bending component includes a bottom plate arranged on the top of the sound insulation board, an extension plate hinged to the bottom plate, and a top plate hinged to the extension plate. A shear component is detachably installed on one end of the top plate away from the sound insulation board.

[0008] Furthermore, the winding assembly includes a shaft, a winding wheel is fixedly mounted on one end of the shaft, a hand wheel is fixedly mounted on the other end of the shaft, and a ratchet is provided on the shaft, and a steering locking mechanism is engaged and connected to the ratchet.

[0009] Furthermore, the steering locking mechanism includes a support seat, a through groove is opened in the center of one side of the support seat, and the shaft is rotatably arranged in the through groove, a rotating shaft is rotatably installed between the two sides of the support seat, one end of the rotating shaft extends out of the support seat and is fixedly installed on the handle, and the rotating shaft is provided with a double-ended pawl that engages with the ratchet.

[0010] Furthermore, a fixing seat is fixedly provided on the side of the support seat away from the ratchet, and the fixing seat is fixedly installed on one side of the sound insulation board. A through groove is commonly provided on one side of the support seat and the fixing seat, and a floating rod is movably provided in the through groove, and a spring is fixedly installed between the floating rod and the through groove.

[0011] Furthermore, two locking inclined surfaces are formed on both sides of the double-end pawl, and a convex key corresponding to the locking inclined surfaces is formed at one end of the floating rod.

[0012] Furthermore, a plug-in board is constructed at the center of the bottom end of the base plate, and the plug-in board is plugged into the top end of the sound insulation board. The tops of both sides of the sound insulation board are movably provided with fixing bolts that are threadedly connected to the plug-in board. Two slots are symmetrically provided on both sides of the top end of the sound insulation board, and two plug-in keys are symmetrically constructed on the tops of both sides of the plug-in board, and the plug-in keys are plugged into the slots.

[0013] Furthermore, rubber sound insulation pads are arranged between the bottom plate and the extension plate, and between the extension plate and the top plate, and two positioning keys are symmetrically constructed on one side of the rubber sound insulation pad. Positioning grooves are centrally provided at the top of one side of the bottom plate, the two ends of one side of the extension plate, and the bottom end of one side of the top plate, and the positioning keys are inserted into the corresponding positioning grooves.

[0014] Furthermore, the shearing assembly includes a mounting seat, which is fixed to the top of the top plate by bolts, and a cutting plate is constructed on one side of the mounting seat, and a plurality of serrated grooves are equidistantly provided on one end of the cutting plate away from the mounting seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model achieves noise isolation through the cooperation of the sound insulation board with the arc-shaped inward bending component. If the buildings on both sides of the bridge construction site are high, the shaft with the winding wheel can be driven to rotate by rotating the hand wheel, so that the rope is wound by the winding wheel, thereby synchronously pulling the bottom plate, extension plate and top plate with the rotating wheel seat to bend to the side away from the building, thereby cooperating with the sound insulation board to block the noise, and avoiding the problem that the residents on the upper side are affected by the higher noise intensity due to the height difference between the bridge and the building, realizing adjustable noise isolation and greatly improving the sound reduction effect of bridge construction. The rope is wound up by the winding assembly, thereby completing the bending of the arc-shaped inward-bending assembly. The shaft rod equipped with the winding wheel is driven to rotate by shaking the handwheel, and the ratchet is locked by the double-end pawls to avoid the problem of winding back. When the locking direction needs to be adjusted, the double-end pawls are pressed to push the floating rod extrusion spring, and the fit state between the convex key on the floating rod and the corresponding locking inclined surface is adjusted, so that the ratchet is locked by the other end of the double-end pawl to facilitate the change of the rotation direction of the winding wheel, thereby effectively improving the stability of the bending degree of the arc-shaped inward-bending assembly.

A first support frame 6 and a second support frame 7 are respectively provided at the bottom of both sides of the sound insulation board 1 for supporting the sound insulation board 1.

[0029] The arc-shaped inward-bending component 2 includes a bottom plate 201, an extension plate 202, and a top plate 203. The bottom plate 201, the extension plate 202, and the top plate 203 are hingedly connected in sequence, and the noise is blocked by the sound insulation board 1 in conjunction with the arc-shaped inward-bending component 2. A plug-in plate 209 is provided at the center of the bottom end of the bottom plate 201, and the plug-in plate 209 is plugged into the top of the sound insulation board 1.

Two slots 101 are symmetrically provided on both sides of the top of the sound insulation board 1, and two plug-in keys 210 are symmetrically provided on the tops of both sides of the plug-in plate 209. The plug-in keys 210 are plugged into the slots 101. Between the bottom plate 201 and the extension plate 202, and between the extension plate 202 and the top plate 203 are arranged with rubber sound insulation pads 207, and two positioning keys 208 are symmetrically provided on one side of the rubber sound insulation pad 207. Positioning grooves are opened in the center of the top of the bottom plate 201, the two ends of the extension plate 202 and the bottom of the top plate 203.

The gaps between the bottom plate 201 and the extension plate 202 and between the extension plate 202 and the top plate 203 are blocked by the rubber sound insulation pads 207 to further ensure the corresponding noise isolation effect.

If the buildings on both sides of the bridge construction site are high, the reel 301 with the reel 302 can be rotated by rotating the hand wheel 303, so that the rope 4 is reeled in by the reel 302, thereby synchronously pulling the bottom plate 201, the extension plate 202 and the top plate 203 with the rotating wheel seat 204 to bend toward the side away from the building, thereby cooperating with the sound insulation board 1 to block noise, and avoiding the problem that the residents on the upper side are affected by the higher noise intensity due to the height difference between the bridge and the building, realizing adjustable noise blocking and greatly improving the sound reduction effect of bridge construction. The rope 4 is wound up by the winding assembly 3, thereby completing the bending of the arc-shaped inward bending assembly 2. The shaft 301 provided with the winding wheel 302 is driven to rotate by shaking the hand wheel 303.

[0032] In order to effectively improve the stabilization effect of the bending degree of the arc-shaped inward bending component 2, a steering locking mechanism 5 is provided.

When the locking direction needs to be adjusted, the double-end pawl 503 is pressed to push the floating rod 506 to squeeze the spring 507, and adjust the fitting state of the convex key 508 on the floating rod 506 and the corresponding locking inclined surface 509, so that the ratchet 304 is locked by the other end of the double-end pawl 503, so as to facilitate the change of the rotation direction of the winding wheel 302, effectively improving the stability of the bending degree of the arc-shaped inward bending component 2.

[0033] Working principle:

[0034] When in use, the sound insulation board 1 is arranged around the bridge construction area, and the construction noise is blocked by the sound insulation board 1 and the arc-shaped inward bending component 2. If the buildings on both sides of the bridge construction site are high, the shaft 301 with the winding wheel 302 can be driven to rotate by rotating the hand wheel 303, so that the rope 4 is wound by the winding wheel 302, thereby synchronously pulling the bottom plate 201, the extension plate 202, and the top plate 203 with the rotating wheel seat 204 to bend to the side away from the building, and the ratchet 304 on the shaft 301 is locked by the double-end pawl 503 to avoid the problem of winding and rotating, so as to adjust the degree of bending of the arc-shaped inward bending component 2. The combined sound insulation board 1 blocks noise, which can avoid the problem of higher noise intensity for residents on the upper side due to the height difference between the bridge and the building, realizes adjustable noise blocking, greatly improves the sound reduction effect of bridge construction, and when it is necessary to adjust the locking direction, by pressing the double-end pawl 503 to push the floating rod 506 to squeeze the spring 507, adjust the fitting state of the convex key 508 on the floating rod 506 and the corresponding locking inclined surface 509, so that the ratchet 304 is locked by the other end of the double-end pawl 503, so as to facilitate the change of the rotation direction of the winding wheel 302, effectively improving the stability of the bending degree of the arc-shaped inward bending component 2.
